NOTE
The bits of this register are implemented with EEPROM cells. Programming and
erasing follow normal EEPROM procedures. The erased state of CONFIG is $0F.
A new value is not readable until after a subsequent reset sequence. CONFIG can
only be programmed or erased in special modes.
NOSEC — EEPROM Security Disable
Refer to 4 Electrically Erasable Programmable Read-Only Memory (EEPROM).
NOCOP — COP system disable
0 = COP enabled (forces reset on timeout)
1 = COP disabled (does not force reset on timeout)
ROMON — ROM Enable
Refer to 2 Operating Modes and Memory Maps.
EEON — EEPROM Enable
Refer to 2 Operating Modes and Memory Maps.
